Abstract: In the regulation of the ink supply according to colorimetric or densitometric parameters, process-related influences for optimum adaptation to the printing process and to the colour sensitivity of the human eye should not be left unconsidered during printing. …<??>For single-colour and multi-colour regulation, methods are therefore proposed which actuate an intended location (Soll) considering the independent boundary conditions - maximum permissible tonal value increase(s) and maximum permissible ink film thickness(s), which intended location is situated both within the tolerable tonal value increase(s) (ZSoll +/- ZTol or ZSolli +/- ZToli) and within the colour tolerance (ETol) or density tolerance (DVTol) or within the tolerance area (TolR). If the intended location (Soll1) does not fulfil these two independent boundary conditions simultaneously, the tolerance range of the tonal value increase(s) is widened and an intended location (Soll2 or Opt) is checked to establish whether it now obeys both boundary conditions simultaneously.

Abstract: Cross modulation interference free AM radio receiver with precise channel selection includes an RF amplifying circuit for amplifying an incoming radio frequency (RF) signal through an antenna (1 ; 101) to output a wide band RF signal and an automatic gain control (AGC) circuit (7 107) for controlling the gain of the RF amplifying circuit in accordance with the field strength of the wide band RF signal. The AM radio receiver further includes a circuit (3, 4, 5, 6 ; 109, 110, 111, 112, 113) for extracting a desired signal from a wide band RF signal, and a first control circuit (81 ; 114, 116, 118) for controlling AGC effect of the AGC circuit in accordance with a field strength of a desired signal. The first control circuit reduces AGC effect as the field strength of the desired signal decreases. Reduced AGC effect increases the amplification rate of the RF amplifying circuit. The AM radio receiver further includes a second control circuit (82) for making the first control circuit non-operative in response to an instruction of an automatic channel selection. At an automatic channel selection, the AGC circuit performs an AGC operation only in accordance with a field strength of a wide band RF signal. The AM radio receiver further includes a third control circuit (118) for setting AGC circuit in forced AGC state where the gain   of the RF amplifying circuit is minimized when the field strength of the desired signal is above a first reference value, and a sensitivity switching circuit (119) for reducing the sensitivity of the AGC circuit to the wide band RF signal field strength when the field strength of the desired signal is below a second reference value.

Abstract: An electrical circuit breaker has a fixed contact (16) and a moving contact (12) which can be driven relative to the fixed contact (16) by means of a crank arm (32) and a coupling element (18). The coupling element (18) contains a locking device (24) whose axial supporting width can be shortened in a sudden manner when an impacting force is exerted on the moving contact as a result of a high fault current. To this end, the coupling element (18) has an axial guide slot (28) for a sliding piece (26) which interacts with corresponding oblique surfaces (62) of supporting elements (52) resting on the sliding piece (26), by means of chamfered edges (64). A pretensioning force is applied between two supporting elements (52) and the sliding piece (26) by means of leaf springs (48, 50). The described locking device is especially suitable for low-voltage circuit breakers which open to limit the current.

Abstract: A feeding device in accordance with the present invention comprises a lateral feed position sensor (HP1) for detecting that a rotatable cassette is placed in a lateral feed position, a longitudinal feed position sensor (HP2) for detecting that a rotatable cassette (32) is placed in a longitudinal feed position and a control device for controlling a cassette rotating motor based on the input coming from the lateral feed position sensor or the longitudinal feed position sensor, such that the longitudinal or lateral feed position of the rotatable cassette and the longitudinal or lateral feed position of a fixed cassette differ, whereby a situation where the rotatable cassette and the fixed cassette that contain copy paper sheets of the same size, are placed in the same longitudinal or lateral feed position, can be avoided and the time needed for feeding the required amount of copy paper sheets in the apparatus the feeding device is attached to, may be shortened. 
     A feeding device in accordance with the present invention comprises in addition to the above arrangement, a rotation prohibition input device (52) for inputting to the control device an instruction prohibiting the rotation of the rotatable cassette, and is arranged such that the control device cancels the control to the cassette rotating motor in response to the input coming from the rotation prohibition input device. As a result, the time needed for feeding the required amount of copy paper sheets in the apparatus the feeding device is attached to may be shortened, and in addition for example when the rotatable cassette and the fixed cassette contain copy paper sheets of the same size and are placed in the same longitudinal or lateral feed position, a large amount of copy paper sheets can be supplied continuously when necessary.

Abstract: An analysing circuit for an inductive displacement pick-up (10, 11.1, 11.2, 12) exhibits the following functional groups:
 - a square-wave generator (13) for outputting a square-wave signal,
 - a driver stage (14) for supplying the displacement pick-up with an input signal obtained from the square-wave signal,
 - a phase-coupled rectifier (15) which rectifies the output signal from the displacement pick-up, taking into consideration the phase of the square-wave signal,
 - a sample/hold circuit (17) for sampling the rectified output signal at predetermined sampling intervals,
 - and a pulse supply circuit (16) which outputs control pulses for determining the sampling intervals at predetermined times referred to the edges of the square-wave signal, the predetermined times being placed in such a manner that during the sampling intervals defined by them it can be assumed that the output signal has essentially settled after a square-wave pulse has been input into the displacement pick-up. 
<??>Due to the fact that a settled DC signal is sampled and held at the output end, the displacement pick-up voltage (UW) has only very little ripple. If it is also intended to eliminate even this little ripple, this can be done with very simple filtering measures. The circuit is therefore simpler than corresponding circuits operating with sine-wave signals in which an elaborate filter circuit is necessary for smoothing the output signal.
